Reaction Steps

A solution of (±)-cis-4-(2-Amino-6-chloro-9H-purin-9-yl)-2-cyclopentene-1-methanol (530 mg, 2.00 mmol) from Example 4, 3-aminocyclopentyl-1-methanol (276 mg, 24 mmol), triethylamine (1.12 g, 10.98 mmol), and ethanol (20 mL) was stirred at reflux for 5 hours. An additional amount of triethylamine (1.17 g) was then added and the solution was refluxed for 8 additional hours. The solution was allowed to cool to room temperature and 2 mL of 1 N NaOH was added. The solution was concentrated and the residues were placed on silica gel column which was eluted with 10% methanol-chloroform (0.36 g, 52%). Recrystallization of such a sample from ethanolacetonitrile gave title compound as white powder, m.p. 177-180° C.
